Rotronic calibration devices are small, airtight chambers that fit any 5/12/15/25 mm probes precisely (Rotronic standard 15/25mm). The lower part of the device consists of a screw-on lid into which the humidity standard is poured on to an absorbent textile pad. The specified humidity is generated in the calibration device after a stabilisation period. High humidity values require a longer stabilisation period. The probe can then be calibrated or adjusted by comparison with the reference value of the humidity standard.
It is straightforward to calibrate your Rotronic humidity probes on-site when using the right calibration device, Humidity standard and the HygroSoft software.
